Python If AND
You can combine multiple conditions into a single expression in Python conditional statements like Python If, If-else and Elif statements. This avoids writing multiple nested if statements unnecessarily.
Examples
In the following examples, we will see how we can use Python AND logical operator to form a compound logical expression.
1. Python If with AND Operator
In the following example, we will learn how to use AND logical operator, in Python If statement, to join two boolean conditions to form a compound expression.
To demonstrate the advantage of and operator, we will first write a nested if, and then a simple if statement where in this simple if statement realizes the same functionality as that of nested if.
Python Program
a = 5
b = 2
# Nested if
if a==5:
if b>0:
print('a is 5 and',b,'is greater than zero.')
# Or you can combine the conditions as
if a==5 and b>0:
print('a is 5 and',b,'is greater than zero.')Here, our use case is that, we have to print a message when a equals 5 and b is greater than 0. Without using and operator, we can only write a nested if statement, to program out functionality. When we used logical and operator, we could reduce the number of if statements to one.
Output
a is 5 and b is greater than zero.
a is 5 and b is greater than zero.2. Python If-Else with AND Operator
In the following example, we will use and operator to combine two basic conditional expressions in boolean expression of Python If-Else statement.
Python Program
a = 3
b = 2
if a==5 and b>0:
print('a is 5 and',b,'is greater than zero.')
else:
print('a is not 5 or',b,'is not greater than zero.')Output
a is not 5 or 2 is not greater than zero.3. Python elif with AND Operator
In the following example, we will use and operator to combine two basic conditional expressions in boolean expression of Python elif statement.
Python Program
a = 8
if a<0:
print('a is less than zero.')
elif a>0 and a<8:
print('a is in (0,8)')
elif a>7 and a<15:
print('a is in (7,15)')Output
a is in (7,15)Summary
In this tutorial of Python Examples, we learned how to use Python and logical operator with Python conditional statement: if, if-else and elif with well detailed examples.
Frequently Asked Questions
if and in Python?Answer:
Yes, you can use the and keyword in Python within an if-statement to check if multiple conditions are all true. When you use if with and, all conditions must evaluate to True for the entire expression to be True. If any one of the conditions is False, the entire expression is considered False.
x = 5
y = 10
if x == 5 and y == 10:
print('Both x is 5 and y is 10')In this example, the print statement will be executed because both conditions x == 5 and y == 10 are true. If either condition were false, the print statement wouldn't execute.
and do in Python?Answer:
In Python, an if-statement with the and keyword is used to combine multiple conditions. The and operator returns True if all the conditions it connects are true. If any one of the conditions is false, the entire expression evaluates to False.
if condition1 and condition2:
# code to execute if both condition1 and condition2 are Trueand operator with an if-statement?Answer:
You use the and operator with an if statement in Python when you need to check that multiple conditions are all true before executing a block of code. It's particularly useful when you have several conditions that must all be satisfied for a certain action to take place.
